What is the commutative property of addition?

a + b = b + a (correct)

a × b = a - b

a × b = a + b

a + b = a - b

Which of the following properties is not applicable to subtraction and division?

Multiplicative property of 1

Commutative property (correct)

Associative property

Distributive property

What is the associative property of multiplication?

(a × b) × c = a × (b × c) (correct)

(a × b) × c = a × (b + c)

(a + b) × c = a + (b × c)

(a × b) × c = a × (c × b)
